Description

Technical Field

[0001] This utility model relates to the field of oil storage tank technology, specifically an oil storage tank with a pressure relief structure. Background Technology

[0002] Oil storage tanks are containers used to store oil products, and they typically have a relatively regular shape. Based on the construction materials, oil storage tanks can be divided into metal tanks and non-metal tanks. Steel tanks are the most common type of metal tank, while non-metal tanks have been gradually phased out due to their greater safety hazards.

[0003] A search revealed patent application CN201721823122.6, which discloses a chemical storage and transportation tank with a pressure relief function. The tank includes a base and a tank body. The bottom of the tank body is connected to the base, and a support rod is connected to the lower part of the base. A first spring is sleeved on the outer wall of the support rod, and the end of the first spring is connected to a fixed seat. An overflow groove is connected to the top of the tank body, and a pressure relief valve communicating with the tank body is installed inside the overflow groove. A cap is screwed onto the top of the pressure relief valve, and a piston is connected inside the cap via a second spring. An overflow hole is provided on the side wall of the pressure relief valve. In this invention, a base is installed at the bottom of the chemical storage and transportation tank body, and a support rod slides between the base and the fixed seat. A first spring is installed on the outside of the support frame. During transportation, the spring at the bottom of the tank provides a certain degree of shock absorption, thereby ensuring transportation safety.

[0004] However, this patent has its shortcomings. This type of oil tank mainly uses a spring-loaded pressure relief valve for pressure relief. Because springs are prone to corrosion and elastic fatigue during use, their overall service life is short and their durability is poor. Furthermore, the spring-loaded pressure relief valve can only relieve pressure at a fixed pressure and cannot be adjusted. As the service life of the oil tank decreases, its pressure resistance will gradually weaken. If the initial pressure value is maintained for pressure relief, it is easy to cause untimely pressure relief and lead to the oil tank rupture.

[0005] Therefore, we propose an oil storage tank with a pressure relief structure. Utility Model Content

[0006] The purpose of this invention is to provide an oil storage tank with a pressure relief structure to solve the problems mentioned in the background art.

[0022] Please see Figures 1 to 4This utility model provides an oil storage tank with a pressure relief structure, including a movable frame 1 and a tank body 2. The tank body 2 is fixedly installed on the movable frame 1. A pressure sensor 4 is fixedly installed at the top of the tank body 2. A pressure relief pipe 8 is fixedly installed at the top of the tank body 2 to the left of the pressure sensor 4. A conveying pipe 11 is fixedly installed to the left of the pressure relief pipe 8. A processing box 13 is fixedly installed at the left end of the conveying pipe 11. A cover pipe 17 is inserted into the processing box 13. Multiple activated carbon blocks 12 are fixedly installed inside the cover pipe 17. An opening 18 is opened at the top of the cover pipe 17 to the left of the activated carbon blocks 12. A sealing plate 20 is fixedly installed at the bottom of the conveying pipe 11 inside the pressure relief pipe 8. A connector 23 is rotatably connected inside the sealing plate 20. The top of the connector 23 extends out of the sealing plate 20 and is fixedly installed with an adjusting plate 19. A transmission rod 9 is fixedly installed at the top of the adjusting plate 19. The top of the transmission rod 9 is rotatably connected inside the pressure relief pipe 8.

[0023] A motor 10 is fixedly installed at the top of the pressure relief pipe 8. The output end of the motor 10 is fixedly installed on the transmission rod 9. The motor 10 drives the transmission rod 9 to rotate, which is beneficial to the use of this equipment. The adjusting plate 19 is provided with first slots 21 on both sides of the transmission rod 9. The sealing plate 20 is provided with second slots 22 corresponding to the two first slots 21. This design is beneficial to the use of this equipment. A threaded seat 15 is fixedly installed at the left end of the cover pipe 17. A threaded ring 16 is fixedly installed on the left side of the processing box 13. The threaded seat 15 is threadedly connected to... The threaded ring 16 is designed to facilitate the disassembly and assembly of the threaded seat 15. An exhaust pipe 14 is fixedly installed at the top of the treatment box 13, which facilitates the discharge of treated gas. A PLC controller 3 is fixedly installed at the front end of the treatment box 13, which facilitates the control of the equipment. An oil outlet pipe 6 is fixedly installed on the left side of the tank 2, and an oil inlet pipe 5 is fixedly installed on the right side of the tank 2. Valves 7 are rotatably connected to both the oil inlet pipe 5 and the oil outlet pipe 6, which facilitate the storage or removal of gasoline.

[0024] Working principle: During use, the device can be electrically connected to an external battery via a connecting cable. When the pressure sensor 4 detects that the gas pressure inside the tank 2 is too high, the motor 10 drives the regulating disc 19 to rotate, causing the two first slots 21 and the second slot 22 to overlap. At this time, gasoline vapor will quickly be discharged through the first slots 21 and the second slot 22, and then enter the cover pipe 17 through the conveying pipe 11. After being filtered and adsorbed by multiple activated carbon blocks 12, the vapor is discharged through the exhaust pipe 14. When the gas pressure inside the tank 2 returns to normal, the motor 10 continues to work, driving the regulating disc 19 to rotate, causing the first slots 21 and the second slot 22 to overlap. By offsetting the two parts, the inside of the tank 2 can be sealed. When the activated carbon block 12 needs to be replaced, turn the threaded seat 15 so that the threaded seat 15 is disengaged from the threaded ring 16, and then pull the threaded seat 15 to the right to pull out the cover tube 17 for replacement. This type of oil storage tank with pressure relief structure is easy to use. The above components can monitor the gas pressure inside the tank 2 in real time and automatically perform pressure relief and exhaust. The pressure relief structure is more durable and has a longer service life. At the same time, the pressure relief pressure can be adjusted according to the service life of the tank 2 to meet the pressure relief needs of different pressures. It can also filter the gas discharged during the pressure relief process before discharge to avoid environmental pollution.
